My gggg grandfather is David Manley. His brother, Levi Manley, married Malinda Nickens on April 1, 1829 in Wilson County, TN. Based on the records I have, Malinda Nickens is the daughter of Francis and William Nickens. So, does this make us cousins-in-law?
Years ago when I first started my family research, there was a Nickens researcher who had created a freepages site. I think her name was Jan, and I think she may have worked at a college in Colorado.
